Different uppercase letters (AB) represent significant differences in the Doppler parameters of the respective region between the post-pubertal and pre-pubertal dogs (P <0.05). Different Greek letters (αβγ) represent significant differences in the Doppler parameters between regions of the Artery (P <0.05).
